Description

Technical Field

[0001] This utility model relates to the field of power pole technology, specifically a welding device for the production of power poles. Background Technology

[0002] Power poles are crucial structures used to support power lines in power distribution and transmission systems. Their primary function is to increase the distance between cables and the ground, ensuring the safe and stable transmission of electricity. Power poles are mainly divided into steel towers, concrete towers, and wooden poles. Steel towers are the most common type of transmission tower, widely used due to their strong load-bearing capacity and good wind resistance. Steel towers are typically hot-dip galvanized to prevent corrosion. The design and construction of power poles must meet strict safety standards, including wind and snow load capacity and seismic resistance, to ensure safe operation under various weather conditions. However, existing welding equipment used in the production of power poles still has certain defects; for example:

[0003] The application CN202420420874.1, entitled "A welding device for the production of power poles", includes: a base, a support seat installed on the top of the base, two support seats, a rotating shaft rotatably connected to each of the two support seats, an adjusting seat fixedly connected to the end of the rotating shaft, a first threaded rod rotatably connected inside the adjusting seat, and a movable frame rotatably connected to the first threaded rod. This utility model, through the coordinated arrangement of adjustable seats, movable frames, and fixed plates, can splice and fix side plates of different specifications. The joint after splicing is located directly below the welding machine, allowing workers to perform straight-seam welding on the side plates simply by moving the welding machine, eliminating the need for alignment. Furthermore, through the coordinated arrangement of worm gears, worm wheels, and rotating shafts, the plates can be flipped after welding the top surface without disassembling and re-fixing them. As can be seen from the above, although this welding device for power pole production can be used effectively, it cannot provide semi-automatic assisted feeding of raw materials during welding. Manual flipping of the raw materials is still required during welding, and the inability to assist in rotating the raw materials makes the welding unstable. Additionally, the distance between the clamps cannot be adjusted according to the length of the raw materials, resulting in poor equipment flexibility and frequent user inconvenience.
